Planned outage: server software upgrades on January 30.

I am planning to be doing some server software upgrades tomorrow. I
don't have an exact time when I'll be starting, nor how long I will be
taking. I will start as early as I can in the morning, and will
continue working until everything is working after the upgrade.
Tech notes:
The server is virtualized using Xen with a Xen0, and three XenU's.
The plan is to upgrade in stages where I upgrade the Xen0 from Fedora
Core 5 to Fedora 8. The XenU's would get matching upgraded kernels (so
they would run from the Xen0), but would otherwise remain on the older
Fedora Core.
Once I am comfortable with that upgrade I will then update the XenU's
(in sequence): calcutta.flora.ca (FLORA.org), hugli.flora.ca
(mail/DNS/etc server), newdelhi.flora.ca (Other websites, Mailman lists,
etc). This later stage is likely to happen on a different day, so that
the downtime of each stage is minimal.
